Pretty sure I'm seeing clearly and Argento is not the master of horror.

I really enjoyed his lighting and score in Suspiria, what I'm wondering is are all his movie's like this? And if I enjoyed Suspiria, what other of his movie's should I look for?

Sleepless. It was damn good.

I'm a big fan of artsy direction, so I obviously loved Suspiria and it's strange lighting, surreal direction, beautiful art-deco/occult sets, and creepy avantgarde soundtrack. It was also my first Argento film. Suffice to say I quickly sought out his other films, and he has since become one of my favorite directors. Suspiria is still my favorite on an artistic level, but I think my all time favorite Argento film is probably Phenomena (though Suspiria and Tenebrae are both close in running).
